34 Troubleshooting
The commonly encountered failures and their solutions are listed below. When you encounter those
problems, please solve them using the corresponding steps. If the problem remains, please contact
SIGLENT as soon as possible.
1. The screen is still dark (no display) after power on:
1) Check whether the power is correctly connected.
2) Check whether the power switch is on.
3) Check whether the fuse is burned out. If the fuse needs to be changed, please contact
SIGLENT timely and return the instrument to the factory for replacement by the
maintenance personnel authorized by SIGLENT.
4) Restart the instrument after finishing the above inspections.
5) If it still does not work correctly, please contact SIGLENT.
2. The signal is sampled but no waveform of the signal is displayed:
1) Check whether the probe is correctly connected to the signal connecting wire.
2) Check whether the signal connecting wire is correctly connected to the BNC (namely
channel connector).
3) Check whether the probe is correctly connected to the item to be tested.
4) Check whether there are signals generated from the item to be tested.
5) Resample the signal.
3. The tested voltage amplitude is greater or lower than the actual value (Note that this problem
usually occurs when the probe is used):
1) Check whether the attenuation coefficient of the channel complies with the attenuation
ratio of the physical probe.
2) Disconnect the oscilloscope from the external signal and do a self-cal.
4. There is a waveform display but not stable:
1) Check the trigger signal source: check whether the source item at the trigger panel
complies with the signal channel used.
